Strava doesn't use heart rate their justification being there are circumstances such as going steep downhill when your heart rate is high but your exertion low. They'd rather just use your weight, speed, distance and topography to estimate.
I doubt any of the systems have got it right so I tend to use the power of the estimated numbers when I get a conflict.
